how many rpms is to much?

Dozer Guy · Jun 15, 2008

I just had my injection pump rebuilt about 2 weeks ago and is running great but something is bothering me. Is it normal, under 3 quarter throttle & light/to med. load for the engine to act like it is running top speed or more R.P.M,s than im youst to? This is a old dozer 64 model td9 IH and doesnt have a R.P.M. guage on it. It acts its miss-fireing [ i.e. studdering ] I really dont how else to explain it but when full load is on it it pushes good & seems to even out. Should I be worried or is it normal? The prev. owner told me when pushing trees or dirt dont ever lugg the motor. Is it governed so the motor wont over rev.& blow up ?? thanks guys!!

It's governed, but it sounds like there is a problem with the governor.

Is there anyway to check it? And could it have tamperd with at the injection rebuilders? I had it re-built again for the 2nd time. 1st time it was just totaly worn out and came back perfect. 2nd time was my fault, I let a tree come into the engine compartment & hit the injection pump instantly seizing the head.I asked them put a good used head on it & they re-calabrated it or whatever they do & I installed. Is it possible I done something wrong? thank you
